It seems to me that in the UK, a substantial minority of people believe in conspiracy theories - such as 9/11 being an inside job. I think it might be increasing. Last week, I was really shocked when I asked a group of 16 year olds how many believed the 'official' version of events in the 9/11 attacks: only 2/20 put their hands up.

To put my cards on the table, my personal belief is that the 'official explanation' of 9/11 is the correct one, and that various alternative theories (like those promoted in the 'Loose Change' film) are wholly wrong. I also believe whole-heartedly that we did go to the moon, that JFK was assassinated by Oswald alone, that humans cause climate change, and that Marilyn Monroe died by her own hand

However, I really don't want to debate the truth or falseness of those beliefs, but I would be interested to know your take on how widespread conspiracy theories are in the USA. I mean, is this just a UK thing, or is it common over the pond too?

What proportion of US people do you think question the 'standard explanation' when it comes to things like: 9/11, the moon landings, JFK's assassination, etc etc.? Or does it vary widly according to which particular event it is?
